rasa-webchat's Issues

Is there any tutorials that could demostrate how to use it ?

It is not loading in IE11, does it supports ES5 browsers?

How to increase the size of the chat windows?

Is there any way to increase the size of the chat window. I wanted to increase its width in a website.

How to increase it?

Send response in raw HTML

Hello!

Is there a way to send a Message as raw HTML?

I've got a custom action that's getting called, generating a Message containing some links retrieved from a database, which then are saved into a slot, which content is than echoed in the the Bots response.

At the Moment, the HTML seems to get escaped, so I'm getting

<a href="http://127.0.0.1/test/****>****Title, where the URL is a clickable Link instead of
just showing ****Title as a clickable Link.

Is there a way of changing this behavior? Is this even a problem with the chat script or is this an issue with Rasa?

(Enhancement) need to integrate speech recognition to the widget

Hi
I'm not a web developer but I wonder if it is possible to integrate speech recognition so that user can choose to chat or speak with the chatbot.

if so how difficult it is to get it up and ready ?

Thanks for your feedback

Stuck in "Waiting for server..."

Hi, i need some help please

Im trying to use the plugin with socket.io in localhost but the chat plugin gets stuck at "Waiting for server..." phase.
This is the code fragment i'm using for the web server:

const server = require('http').createServer();
const io = require('socket.io')(server);
io.on('connection', function(socket){
  console.log('a user connected');
  //console.log(socket)
  io.emit('bot_uttered', {"text": "hola, soy jean pierre el servidor"})
  socket.on('user_uttered',function(message){
    console.log(message);
    return true;
  });
  return true;
});


server.listen(3000);

When the client connects the message from the server is sent but im unable to write from the client side.

im suspecting that it has something to do with
initPayload: "/get_started"
but i havent found anywhere what that options is suposed to do.

Thaks!

Bug with starting a conversation via button click

If you click on a button to open the chat window, it opens the chat (but doesn't send the initial payload). You then chat to it for a bit, then close the window and open it again and then the initial payload gets sent in the middle of the conversation.

This is using version 0.4.2 in the webchat widget, basically it shouldn't send the initial payload if the conversation is already happening

Strong text (** in md) does not appear strong

Guilty seems to be the Roboto font. When commenting the font the text gets bigger
.message {
margin: 10px;
display: flex;
/* font-size: 14px; /
/ font-family: "Roboto", serif; */
}

Buttons disappear immediately, if another message from the bot follows

My bot should utter a message with two buttons and right away another, additional message. Unfortunately the buttons only show up for a fraction of a second and disappear, when the other message from the bot is uttered.

In my point of view the buttons should stay in the chat protocol as long as the user has not answered.

Here how my rasa template lookes like:

utter_intro1:
  - text: "Hi I am ... These are my use cases... "
    buttons:
    - title: "Use Case 1"
      payload: "/a"
    - title: "Use Case 2"
      payload: "/b"
    - title: "Use Case 3"
      payload: "/c"
utter_intro2:
  - text: "...but I am also happy to answer other questions from you..."

Changing Client-Side JavaScript

Hello,

I'm including the webchat widget into my website via a script tag. Now I have to implement some changes and started by downloading the webchat-latest.js which is hard to read because of the optimization. Is there a more readable version somewhere?

Escalation to human

Hi
It is a common requirement to escalate a chat from a chatbot to a human. It would be great if you can integrate a functionality, so that the user manually initiates an escalation or automatically by a special message form the socket.io server.
This could be easily implemented by switching to another, alternative socket.io server if requested by the user or by the special message/event from the socket.io server.

How to run this widget

I'm new to this platform and i developed rasa chatbot now i want to connect this widget to my rasa chatbot how to do that, can anyone please explain in detail.

thanks in advance

Rasa-webchat widget appears to connect to rasa server, but keeps saying "Waiting for server..."

I’m running the Rasa stack starter pack example with the Rasa webchat widget, embedded as JS script, using the Rasa server socketio setup.

It appears to connect successfully (i.e. when running the rasa stack server, I see the log messages that suggest POST and GET request to e.g. /socket.io/?EIO=3&transport=polling&t=MThFYM_&sid=cfc8653cd08d4ba98127487495d5ad6a are successful and return a 200 code, but the web widget on the page continues to say “Waiting for server…” and the user input field stays disabled. There are also no XHR error messages from the web inspector, suggesting the connection to the Rasa stack server works (I can see these errors as soon as I stop the rasa server).

I feel I'm missing something obvious here, but I’m kind of lost trying to figure out what makes the webchat widget think it is not connected to the server - any pointers or suggestions would be very welcome, thanks!

Video/Image Not Showing

Hi there! I'm trying to send a video/image to the chat UI from Rasa but this is what i'm getting:

This is a snippet of my actions.py code:

I have an actions server and my socket server code is on another Python file. If I use the SocketIOOUtput Class, it will ask me for a recipient ID which I'm not sure where to get. I'm pretty new to Python and Rasa. Any help would be much appreciated!

Notification on new incoming messages

Is there a way to get notified when webchat receives any message or is there a way to get the size of messages?

hii

Local storage data should probably be an object (not stringified)

expose `toggleConversation` to the hosting page with js

related to #16

In order to achieve the same behaviour as when a user clicks on the Launcher, it would be awesome to have access to the toggleConversation function as well. Would you be open to that?

Retrieving customData in core actions

I have set a react prop customData={{"userId": "123"}} according to the README page. I have successfully connected rasa-webchat to rasa_core via socketio. I cannot get that customData in my custom rasa_core actions.

Issue: Missing a hint in README on how to retrieve this customData in rasa_core. This may be very useful for many novices like me.

The general problem: Identification of the user in the rasa core actions. To achieve this I need either:

Extract senderId from rasa-webchat component in react frontend and attach this id to the user in the database.
Supply custom senderId or customData to rasa-webchat.

However, I cannot do any of these. I cannot access senderId in the react component. And I cannot set my custom senderId. The rasa-webchat react component is closed.

Waiting for server...

Hi,

I'm new to rasa-webchat, and trying to get it working with an Angular project. SocketIO is running on port 5002, and I can see following GET/POST from the front-end. But no data being exchanged, and UI says "Waiting for server...".

Can anyone please help/advise?

"GET /socket.io/?EIO=3&transport=polling&t=MVz-uNz&sid=a02f3e5509144af494d9e02866296be7 HTTP/1.1" 200 211 25.986784

CORS error connection to RASA running on Docker

I am running RASA on Docker but trying to connect from the webchat I am getting the following error:
Access to XMLHttpRequest at 'http://localhost:5005/socket.io/?EIO=3&transport=polling&t=McN1g06' from origin 'http://localhost:808' has been blocked by CORS policy: The value of the 'Access-Control-Allow-Credentials' header in the response is '' which must be 'true' when the request's credentials mode is 'include'. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

Here my nlu_config.yml
`language: "en"
cors_origins:

"*"
pipeline: "spacy_sklearn"`

Also I created a credentials.yml file
socketio: user_message_evt: user_uttered bot_message_evt: bot_uttered

and added it to the docker-compose command for rasa_core
command: start --core models -c rest --endpoints config/endpoints.yml -u current/ --credentials config/credentials.yml

I am missing something?

PD: Rasa version 0.14

How to send video from rasa core?

How can I send video through rasa core to the webchat? For images, it is straightforward: just setting a "- image: url" in the bot domain file will do the trick. However, there is no '- video' option, only a custom message that could (or could not) be used to send a video instead. Do you think it is an option? Or maybe the only way is adding a 'send_video_url' method in the rasa core socketio class, similar to the send_image_url (https://github.com/RasaHQ/rasa_core/blob/d3a435b6b1b68db90d309d4da38f9247416a825d/rasa_core/channels/socketio.py#L56) method?

Chat window running a custom Action on opening

Hello Everyone,

Thanks for this Chat Widget first of all, I have tried implementing this chat widget, everything works fine except on opening html page chat windows runs a custom action by default which is not supposed to happen.
How to make default utter greet message on first load ?

Please help.

Thanks,

Unable to use Widget Component

Hello. Thanks for this widget, it has a lot of potential.

For two months I use rasa-webchat without using React (only using html and script).

Now using React I'm trying to import the Component to my project using the steps in README, but it appears this error when I try to use the Component:

`

Someone could help me? :(

Persistent sessions across pages

As a bot creator, I would like to persist the state of the conversation in the browser to be able to continue it when the user comes back to the hosting web page, or even across web pages on the same host.

This has 2 impacts:

Session id

The socket session id cannot be safely customized, which means that it cannot be used as a user id (or sender_id in Rasa Core terms). The socket server must implement a store mapping socket ids and the bot session or user id.

On connect:

if the client has a core session stored locally, it attaches it to the socket (e.g. socket.userId = localStorage.get(...)) so when a message is emitted the server can map it to the correct stored conversation.
if the client has no core session stored locally, then the server won't find the socket.userId when it receives a message. That is the signal of a new user or conversation. Then the server will create a user id and attach it to the socket so future messages can be attached to that session.

`SocketIOInput` changes

A SessionStore mapping socket.io id's and core sender_id's must be added. A simple interface that can support several implementations, similarly to the TrackerStore
When a new message comes here (https://github.com/RasaHQ/rasa_core/blob/master/rasa_core/channels/socketio.py#L141) the mapping happens.

Local storage

The conversation can be stored locally under the userId key in the localStorage or sessionStorage. Probably an array of messages in the native format that can be fed to the widget at initialization time.

config

A new prop storage accepting values local and session could be added depending on the persistence required
If not set the conversation vanishes (current behaviour)

Callback / notification when user types a message

Images: expose dimensions as parameters

Links in messages should be highlighted and clickable

See discussion here: botfront/rasa-addons#15

Possibility of sending images from user

I was thinking in the case of a chatbot that can interpret text AND images sent by the user. It is doable? Adding this feature to the chatbot interface?

try use as react component, not showing

there is no error reported , just not showing

any one met this issue?

I also tried react-chat-widget , it can show up

fullScreenMode not working

A similar issue was reported on the original repository, see: Wolox/react-chat-widget/issues/76
Any chance of a fix?

Thanks in advance,

Buttons disappear after user input

Hi,

each new bot message like buttons dissappear after user clicks or bot outputs a new button? That is bad to follow dialogue or when bot utter two buttons like for contact or feedback...

How can I prevent this?

I use it as the script version just shown here:
https://github.com/mrbot-ai/rasa-webchat#as-a-script

Expose show/hide/close/open functions to the hosting page with javascript

var widget = WebChat.default.init(...)
widget.open()
widget.close()
widget.hide()
widget.show()

@TheoTomalty @dliuproduction thoughts?

Show Typing dots when user wait ...

there is a function or an exposed prop that displays 'typing dots' while user waiting for an answer? I can not find it. How have you solved this problem? there is same fork of this project that improve this gui component?

Npm test in bitbucket pipelines : SyntaxError: Unexpected identifier "Import"

I am trying to use rasa-webchat Widget in an new ReactJs project but
when I do npm test in bitbucket pipeline I get the following error

/opt/atlassian/pipelines/agent/build/node_modules/rasa-webchat/index.js:1
({"Object.":function(module,exports,require,__dirname,__filename,global,jest){import React from 'react';

SyntaxError: Unexpected identifier
  1 | import React, { Component } from 'react';

I tried the same code changing the import from rasa-webchat to react-chat-widget and it works fine. So I think there is something wrong happening due to this plugin

I'm using this Docker image on my pipeline: node:11.6.0

Here are my dependencies :

  "dependencies": {

Any help would be appreciated

Images: crop scale image if ratio is different

interacting with webchat from within webpage

Hi all - this is a question rather than an issue/problem as such, hope it's ok to bring it up here.

I have a client requirement where I need to trigger an action/message from the webpage that the Rasa webchat widget is embedded on. E.g. someone clicks on a link on the web page, and a custom action or message appears in the webchat widget that's embedded on that page.

I was vaguely thinking maybe making a POST request to the Rasa action server, duplicating what Rasa Core sends to it, but I'm not sure how to match things like sender ids etc to make that work (if it's even possible).

I realise this may be outside the scope of this, so feel free to close it so, I was just wondering in case anyone here had done something similar before.

UI is just a blank screen

If I run the core as a socket.io server directly as is described in the rasa docs:
https://rasa.com/docs/core/connectors/#socketio-connector
I get polling requests to the Rasa server which return 404s. And the web page is blank.

If I run the core as a socket.io server using python as is described in the rasa docs:
https://rasa.com/docs/core/connectors/#id21
I get polling requests to the Rasa server which return 200s. And the web page is blank.

Is there a a UI served from index.html?
Thanks!

Conditional behavior based on conversation history

As a bot developer, I would like to build conversational flows spreading on several web pages.

Example 1: A customer asks for a shipping update on an e-commerce site. The bot answers with an order shipment link. The user clicks the link and the widget continues the conversation on the new page (e.g.: waits 30 seconds, opens, and pushed a message. But I don't want the widget to pop up any time a user hits or refreshes the page

Example 2: Customer walkthrough. The bot is guiding a user through a web app, page by page. Once the user gets to the next page, (s)he gets the next instruction.

##Implementation idea

On the widget side:

An array of widget_events is stored in the local storage:

{
   url: '' // url regex
   actions: ["show","open","full_screen"], // sequence of widget events
   delay: 10, // delay in second
   expires: UTC timestamp,
   payload: "/intent{'entity':'value'}"
}

When the widget in instantiated on a page, it looks for a match (current url agains the urls in the widget events) in the events stored in local storage. If it finds a match, the event is removed and executed (i.e after the delay, and unless the event has expireed, the sequence in action is executed and the payload sent.

Sending `widget_event`s to the widget.

The easiest way would be to keep using the bot_uttered socket event (instead of using another one)
Then a different type of message could be sent by the server (e.g. Rasa Core), that instead of displaying a message would just create a widget event as described above.

A Core story example:

## story
* whatever_intent
   - utter_follow_that_link  // "Please follow the following link" 
   - action_set_widget_event // Send the widget event

To send the widget event the send_custom_message could be overriden in the SocketIOOutput
The payload would just be the widget event

Possible limitation: the dispatcher send_custom_message only supports the elements object, see if that can be easily overriden

Block user from writing until a response form the chatbot

Often chatbots cannot handle or they become confused because of multiple inputs in a row from the user.

Because of this a common approach is to block the user from writing/input until a response form the chatbot is delivered.

Could you please develop this as a feature that can be enabled in the configuration?

No 'Access-Control-Allow-Origin' header is present on the requested resource.

Hi everyone,

I just tried to use the webchat just as it is described here by Juste.
I can see a 500 code in Chrome's console saying Access to XMLHttpRequest at 'http://localhost:5005/socket.io/?EIO=3&transport=polling&t=MYei2_H' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Also python is facing me with an AttributeError:

I used the html-code provided in dev/src/index.html. Chrome shows an empty page.

What am I missing?

Thanks for your feedbak

On mobile, widget-container overlaps page content even when widget it minimized

It looks like on mobile, the widget-container class overlaps the page content when the widget is minimized/closed, so e.g. links on the page the widget is embedded on are not clickable.

HTML table

Folks, can I send a html table as message? It is rendering as plain text.

Thanks
